DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIG. 8, a prank apparatus in accordance with the present invention comprises a base unit 4, a driving device 5 mounted on the base unit 4, and a decorative unit 6 mounted on the driving device 5.

The base unit 4 includes a housing 41, a sounder 42 mounted in the housing 41, a sensor 43 mounted in the housing 41 and located beside the sounder 42, a power supply 45 mounted in the housing 41, and a control board 46 mounted in the housing 41. The sounder 42 of the base unit 4 is located in the front end of the housing 41 and can emit a sound with an amusement effect. The sensor 43 of the base unit 4 is operable to actuate the driving device 5. In the preferred embodiment of the present invention, the sensor 43 of the base unit 4 is a light sensor, a sound sensor, a footpad control switch, a try-me switch or a combination of the above-mentioned parts. The power supply 45 of the base unit 4 is connected to the driving device 5 to supply an electric power to the driving device 5. The control board 46 of the base unit 4 is located under the power supply 45 and is connected to the sensor 43 to select and control the detection states of the sensor 43.

The driving device 5 is operable by the sensor 43 of the base unit 4. The driving device 5 is mounted on the housing 41 of the base unit 4 and includes a mounting seat 51 mounted on the housing 41 of the base unit 4, a drive wheel 53 rotatably mounted in the mounting seat 51 and having a periphery locally provided with a plurality of drive teeth 54, a drive motor 52 mounted in the mounting seat 51 and connected with the drive wheel 53 to rotate the drive wheel 53, a driven wheel 55 rotatably mounted on the mounting seat 51 and having a periphery locally provided with a plurality of driven teeth 56 meshing with the drive teeth 54 of the drive wheel 53, a support bar 57 connected with the driven wheel 55 to move in concert with the driven wheel 55, and two torsion springs 58 mounted on two opposite sides of the driven wheel 55 and each having a first end connected with the mounting seat 51 and a second end connected with the support bar 57. The driven wheel 55 of the driving device 5 is disposed above the drive wheel 53. The support bar 57 of the driving device 5 is formed on and extended outward from a side of the driven wheel 55. Each of the torsion springs 58 has a substantially V-shaped profile.

In the preferred embodiment of the present invention, the base unit 4 further includes a support rack 47 mounted on the housing 41. The decorative unit 6 is mounted on the support bar 57 of the driving device 5 and the support rack 47 of the base unit 4. The decorative unit 6 includes an extension shank 63 having a first end connected with the support bar 57 of the driving device 5 and a second end provided with an elongate guide slot 64, a movable pin 66 movably mounted in the guide slot 64 of the extension shank 63, a first link 65 having a first end pivotally connected with the movable pin 66, a decorative body 61 connected with a second end of the first link 65, and a second link 67 having a first end pivotally connected with the support rack 47 of the base unit 4 and a second end pivotally connected with the first link 65. The second end of the second link 67 is located between the movable pin 66 and the decorative body 61. The decorative body 61 is movable in concert with the support bar 57 of the driving device 5 and is provided with a connector 62 connected with the second end of the first link 65.

In operation, referring to FIGS. 9-11 with reference to FIG. 8, the base unit 4 is operated and switched to turn on the driving device 5 so that the drive motor 52 can be operated to drive the drive wheel 53. At this time, the user can transmit a signal to the sensor 43. For example, the user can transmit a light-sensitive signal, such as an infrared ray and the like, to the sensor 43. In such a manner, after the sensor 43 receives the signal from the user, the sensor 43 transmits a signal to the control board 46 which starts the drive motor 52 which drives the drive wheel 53 to rotate in the counterclockwise direction as shown in FIG. 9. At this time, the driven teeth 56 of the driven wheel 55 mesh with the drive teeth 54 of the drive wheel 53 so that the driven wheel 55 is driven by the drive wheel 53 to rotate in the clockwise direction so as to move the support bar 57 and the extension shank 63 downward and backward and to compress the torsion springs 58 for storing a restoring force. Subsequently, the drive wheel 53 is further rotated in the counterclockwise direction until the driven teeth 56 of the driven wheel 55 disengage the drive teeth 54 of the drive wheel 53 as shown in FIG. 10 so that the driven wheel 55 is released from the drive wheel 53 and is pushed by the restoring force of the torsion springs 58 to rotate in the counterclockwise direction so as to move the support bar 57 and the extension shank 63 upward. In such a manner, when the support bar 57 and the extension shank 63 are moved upward and forward by the restoring force of the torsion springs 58, the first link 65 is moved upward and forward by a sliding motion of the movable pin 66 in the guide slot 64 said upward and forward motion of the extension shank 63, and the second link 67 is moved upward and forward by push said upward and forward motion of the first link 65 so that the decorative body 61 of the decorative unit 6 is instantaneously sprung upward and forward, and when extension shank 63 reaches a generally vertical orientation, decorative body 61 is permitted to continue its upward and forward motion by a sliding motion of the movable pin 66 in the guide slot 64 of the extension shank 63. At the same time, the sounder 42 can emit a sound when the decorative body 61 of the decorative unit 6 is sprung upward and forward. Thus, after the sensor 43 receives the signal from the user, the decorative body 61 of the decorative unit 6 is sprung upward and forward, and the sounder 42 emits a corresponding sound so as to achieve a video/audio frightening amusement effect. Subsequently, the drive wheel 53 is further rotated in the counterclockwise direction until the driven teeth 56 of the driven wheel 55 mesh with the drive teeth 54 of the drive wheel 53 again as shown in FIG. 11 so that the driven wheel 55 is driven by the drive wheel 53 to rotate in the clockwise direction again so as to move the support bar 57 and the extension shank 63 downward and backward and to compress the torsion springs 58 for storing a restoring force.

In a further preferred embodiment of the present invention, the sensor 43 of the base unit 4 is a contact switch (such as a footpad control switch, a try-me switch or the like). In practice, the sensor 43 of the base unit 4 has a connecting line which has a terminal embedded in a determined position of the housing 41. Thus, when the user touches the terminal of the connecting line of the sensor 43, the sensor 43 of the base unit 4 is operated to actuate the driving device 5.

Accordingly, after the sensor 43 receives the signal from the user, the decorative body 61 of the decorative unit 6 is initially moved downward and backward slowly and then sprung upward and forward suddenly, and the sounder 42 emits a corresponding sound simultaneously. In addition, the sensor 43 of the base unit 4 is operated in an optical, acoustical and manual contact manner so that the user can control the sensor 43 to actuate the driving device 5 so as to move the decorative body 61 of the decorative unit 6 easily and quickly.
